摘  要:
本研究收集、分离和鉴定了约250个代表广泛地理来源、寄主范围和病害类型的Rhizoctonia solani 分离物。通过菌丝融合测定,把这些分离物分别归入AG1-AG5 5个菌丝融合群。用土壤覆盖培养法,诱导使AG2-1和AG4的各1个分离物产生了有性世代,鉴定结果表明它们都属于Thanatephorus cucumeris(Frank)Donk。本文对各融合群分离物的病理学、生态学和分类学问题作了初步的讨论。

摘  要:
About 250 isolates of Rhizoctonia solani,representing a wide range ofgeographic origins,hosts and types of diseases in China,were collectedand identified.According to anastomosis,these isolates belong to fiveanastomosis groups(AG1—AG5),which were consistent with Parmeter& whitney's(1969)and Ogoshi's(1972)groups.With the way of soil over-culture,each one of AG2-1 and AG-4 isolates was induced to produceperfect stage in vitro,their identificaion turned out to be Thanatephoruscucumeris.(Frank)Donk.The pathogenic,ecological and taxonomicalimplications were discussed.
